Nā waiwai palaki o ka lāʻau maʻamau

1. Lapa maoli
He mea maʻalahi ka loaʻa ʻana o ka palaka kūlohelohe. ʻO ka viscosity mau a me ka viscosity haʻahaʻa maleic rubber maʻamau he haʻahaʻa ka viscosity mua a maʻamau ʻaʻole pono e hoʻopili ʻia. Inā ʻoi aku ka viscosity Mooney o nā ʻano mea hoʻopili maʻamau ma mua o 60, pono lākou e hoʻoheheʻe ʻia. Ke hoʻohana nei i kahi huila kūloko no ka hana ʻana, ʻo ka manawa ma kahi o 3-5 mau minuke ke piʻi ka mahana ma luna o 120 ℃. I ka hoʻohui ʻana i nā plasticizers a i ʻole plasticizers, hiki iā ia ke hōʻemi nui i ka manawa plasticizing a hoʻomaikaʻi i ka hopena plasticizing.
2. Styrene-butadiene
ʻO ka ʻōlelo maʻamau, ʻo ka Mooney viscosity o Styrene-butadiene ka hapa nui ma waena o 35-60. No laila, ʻaʻole pono ʻo Styrene-butadiene i ka plasticizing. Akā ʻo ka ʻoiaʻiʻo, ma hope o ka plasticizing, hiki ke hoʻomaikaʻi ʻia ka dispersibility o ka mea hoʻohuihui, e kōkua ana i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana. Maikaʻi no nā huahana pāpaʻi sponge, ua maʻalahi ʻo Styrene-butadiene i ka huʻa ma hope o ka plasticating, a ua ʻano like ka nui o ka bubble.
3. Polybutadiene
Loaʻa i ka Polybutadiene ka waiwai kahe a ʻaʻole maʻalahi e hoʻomaikaʻi i ka hopena plasticizing. I kēia manawa, ua hoʻomalu ʻia ka Mooney viscosity o Polybutadiene i hoʻohana mau ʻia ma kahi ākea kūpono i ka wā polymerization, no laila hiki ke hoʻopili pololei ʻia me ka ʻole o ka plasticizing.
4. Neoprene
ʻAʻole pono e hoʻopili ʻia ʻo Neoprene, akā ma muli o kona paʻakikī kiʻekiʻe, kōkua ia i ka hana. He 30 ℃ -40 ℃ ka mahana wela maʻamau, maʻalahi ke pili i ka ʻōwili inā kiʻekiʻe loa.
5. Ethylene propylene rubber
Ma muli o ke ʻano saturated o ke kaulahao nui o ka Ethylene propylene rubber, paʻakikī ke hana i ka molecular cracking e ka plasticating. No laila, ʻoi aku ka maikaʻi o ka synthesize i loaʻa kahi viscosity Mooney kūpono me ka ʻole o ka pono no ka hoʻoheheʻe ʻana.
6. ʻO ka pahu butyl
He paʻa a paʻa ka paʻa paʻa o ka butyl rubber, liʻiliʻi molecular paona a me ka wai nui, no laila ʻaʻole maikaʻi ka hopena plasticizing mechanical. Hiki ke hui pono ʻia ka ʻōpala Butyl me ka viscosity haʻahaʻa Mooney me ka ʻole o ka plasticizing.
7. Puka Nitrile
He liʻiliʻi liʻiliʻi ʻo Nitrile rubber, paʻakikī kiʻekiʻe a me ka hana wela nui i ka wā plasticating. No laila, hoʻohana pinepine ʻia ka haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa a me ka plasticating segmented i ka wili ākea e loaʻa ai nā hopena maikaʻi. ʻAʻole pono e hoʻopili ʻia ka lāʻau nitrile i loko o ka mea hui kūloko. No ka loaʻa ʻana o ka palaka Nitrile palupalu, hiki ke hui pū ʻia me ka ʻole o ka hoʻomaʻemaʻe ʻana i ka plastic.
